Green Building Certification: LEED, Energy Star, Passive House, and Net Zero Certification Programs

Green Building Rating Systems LEED certification evaluates building performance across categories including sustainable sites, water efficiency, energy and atmosphere, materials and resources, and indoor environmental quality. Projects earn points in each category, with Certified, Silver, Gold, and Platinum levels. The Energy Star program certifies buildings that achieve energy performance in the top 25 percent of […]

Construction Codes and Standards: Building Codes, Zoning Regulations, Permitting Processes, and Code Compliance

Building Code Requirements The International Building Code is the model code adopted by most states and local jurisdictions for regulating building construction. The code establishes minimum requirements for structural safety, fire protection, accessibility, energy efficiency, and other aspects of building performance. The code is updated on a three-year cycle to incorporate new knowledge and technologies.

Construction Accounting and Financial Management: Job Cost Systems, Percentage of Completion, and Cash Flow Management

Construction Accounting Methods Construction accounting differs from general accounting because of the long-term nature of construction projects and the need to match revenues with costs over the project life. The percentage of completion method recognizes revenue and expenses as the project progresses based on the percentage of work completed. The percentage complete is determined by

Fire Protection Engineering: Sprinkler Systems, Fire Alarms, Passive Fire Protection, and Building Code Requirements

Fire Protection Systems Fire protection systems in buildings include active systems such as sprinklers and standpipes, and passive systems such as fire-rated construction and compartmentation. The building code requirements for fire protection depend on the building occupancy type, height, and area. Automatic sprinkler systems are the most effective active fire protection measure. NFPA 13 governs

Construction Safety Planning: Job Hazard Analysis, Competent Person Requirements, and Site Safety Programs

Site Safety Planning Site safety planning begins before construction starts with the development of a project-specific safety plan. The plan identifies the hazards associated with each phase of construction and specifies the control measures to be implemented. The competent person designation assigns responsibility for safety oversight to individuals with the training and authority to identify

Construction Labor Relations: Prevailing Wage Requirements, Collective Bargaining, and Workforce Development

Construction Labor Relations Labor relations in construction involve the relationships between employers and workers, including the negotiation and administration of collective bargaining agreements. The Davis-Bacon Act requires that workers on federally funded construction projects be paid prevailing wages determined by the Department of Labor. Prevailing wages are based on the wages paid to the majority

Prestressed Concrete Bridge Design: Girder Design, Prestress Losses, and AASHTO LRFD Specifications for Highway Bridges

Prestressed Bridge Girder Design Prestressed concrete bridge girders use high-strength steel strands tensioned before or after concrete placement to introduce compressive stresses that counteract tensile stresses from loads. This allows longer spans and shallower sections than reinforced concrete. The AASHTO LRFD specifications govern the design of prestressed bridge girders. The prestressing force is designed to
